News

Our SIGIR 2010 paper on search intent is featured in New Scientist; and in another piece on applications to search advertising.

Giving invited talks at the SIGIR 2010 workshop on Query Understanding and at the workshop on Feature Generation for IR.

Initial results on our new web-based cognitive diagnostic test to be presented at Soc. for Neuroscience annual meeting.

Slides for my WWW 2010 tutorial on Inferring Searcher Intent posted. Will present an expanded version at AAAI 2010.

Research

I lead the Emory Intelligent Information Access Lab (IRLab). We work on information retrieval and text and data mining, developing techniques for mining user behavior and interactions in web search and online social networks, large-scale content analysis and information extraction, and on applications of these techniques to medical informatics.

I am also affiliated with the Emory Data Management Group, The Emory Center for Comprehensive Informatics, and the Georgia Institute of Technology Web Science Initiative.
